6 Claims. 1

This invention relates to plumbing fixtures useable in sanitation systems and, more particularly, to an improved flush toilet.

Perhaps the greatest disadvantage of common flushing toilets, is the excessive noise associated with the flushing function. The inrush of water from the storage tank into the bowl of the toilet creates a great deal of unnecessary and un- To overcome this disadvantage of the usual toilet it is proposed to provide a toilet with silencing attachments, one of which may be installed in the pipe leading from the storage tank to the toilet bowl, and the other of which may be detachably secured over the water orifices leading into the said bowl.

One object of the invention is the provision of a flush toilet which is quiet in its flushing operation.

A further object of the invention is the provision of a silencing attachment useable in fiush.

toilets, which is simple in design, easy to install,

usual flush toilets, and cheap to manufacture.

Yet another object of the invention is the provision of a flush toilet having an aerating device disposed in the pipe leading from the storage tank to the bowl of the said toilet.

Another and more detailed object of the invention is the provision of an attachment which may be installed in flush toilets, and is operable to subdivide the usual streams of water rushing into the toilet bowl into a plurality of finely divided streams of aerated water.

With these and other objects in view which may appear while the description proceeds the invention consists of the novel arrangement of cooperating parts shown in the accompanying drawings forming part of this application and in which- Figure 1 is a top plan view of one embodiment of the invention showing a silencing member installed in a flush toilet;

Figures 2 is a top plan view of the said silencing member;

Figure 3 is an elevational view illustrative of one way in which the said silencing member may be hinged for installation in the said toilet;

Figure 4 is an enlarged partial elevational view showing the said silencing member in place in the said toilet, and one means by which the said member may be secured;

Figure 5 is a similar view illustrative of the communicative connection between the said silencing member and the main water conduit of the said toilet, and

- Figure 6 is an elevational view of one form of the said fastening means.

Referring more in detail to the drawings in ber, plastic or spring steel. The said gasket,

preferably, is hinged along its major axis, and is secured to the upper inner edge of the rim of the toilet in by a plurality of fastening means,

one form of which is hereinafter described in greater detail. The upper surface of the gasket 12 is provided with a plurality of recessed portions or troughs 13 into which is directed, the water for flushing the said toilet. Each said recessed portion or trough is provided with a i plurality of screened ducts M for aerating the said water on its passage to the bowl of the toilet Ill.

The said ducts may be of any cross section and dimensions suited to the intended application, but, preferably, are internally bafiled tubular ducts communicatively connecting the troughs l3 to the bowl of the toilet [0. Each duct M'is provided with an upper terminal flange recessed in the said gasket at the base of the said troughs, and is formed with a plurality of peripheral slots disposed at a region immediately below the gasket 12, through which, air may be drawn into the said duct for aerating the water passing therethrough. A plurality of finely apertured bafiles are stacked within the duct and serve to finely divide the said water during passage there through.

In order further to silence the sudden rush of water during flushing, the pipe leading from the storage tank II to the bowl of the toilet in is also provided with an aerating device l5 formed generally as hereinbefore described and in communicative connection with the atmosphere.

One form which the fastening means may take is illustrated in Fig. 6 of the drawing, wherein is shown a terminally threaded bolt it of flexible elastic material; e. g.--spring steel, having its upper half split into two outwardly upwardly disposed terminally flanged portions. A washer 1-1 and nut it are provided for each said bait,

In operation, the gasket is folded, placed in the bowl of the toilet H] and secured in place under the inner top edge of the said bowl by the bolts H5, washers i1 and nuts It. The said bolts are inserted through the usual water inlets l9 leading into the toilet [0. Water released from the storage tank Ii flows to the main conduit of the said toilet from whence it is received in the troughs 13 of the gasket [2 via the remainder of the (times is, and is then discharged through the ducts I4. It is evident that the water will be divided into a multiplicity of inherently quiet aerated streams thus silencing the fiushin'g action It is believed that the construction and eaten; tages of the structure shown may be apparent from the foregoing paragraphs taken in eonjunction with the accompanying drawings without further detailed description.
